A Zimbabwean work that is in the public domain in Zimbabwe according to this rule is in the public domain in the U.S. only if it was in the public domain in Zimbabwe in 1996, e.g. if it was published before 1946 and no copyright was registered in the U.S.
A Lay-Up process is a moulding process for composite materials, in which the final product is obtained by overlapping a specific number of different layers, usually made of continuous polymeric or ceramic fibres and a thermoset polymeric liquid matrix. It can be divided into Dry Lay-up and Wet Lay-Up, depending on whether the layers are pre ...
Zimbabwe's arable land surface is relatively small compared to major food producers in Africa, but its agriculture was rather well performing from 1961 to 2001 (up to 10% of African maize production in 1985). There are five natural regions that make up the agriculture of Zimbabwe. The first three regions are used for producing crops. [5]
Given the country's solid knowledge base and abundant natural resources, Zimbabwe has the potential to figure among the countries leading growth in sub-Saharan Africa. [1] [2] Zimbabwe was ranked 118th in the Global Innovation Index in 2024. [5] To do so, however, Zimbabwe will need to correct a number of structural weaknesses.
Production began in 1958, [3] and in 1959 the properties were sold to a Rio Tinto subsidiary Rio Tinto Zinc (RTZ). [1] The mines were first worked by filling a wheelbarrow with the gem containing soil and then washing away the earth, [ 4 ] but were replaced by modern placer techniques.
It is a group of layered ultramafic intrusions that extend across Zimbabwe with a strike of about N20°E. The width of the intrusions vary from 3 to 12 km (7.5 mi). The Great Dyke is unusual in that most ultramafic layered intrusions display near horizontal sill or sheet forms.
Zimbabwe's agriculture and livestock sectors face challenges from changing climate conditions, including reduced crop yields, water scarcity, and impacts on livestock production. [22] Climate change will result in the emergence of new pests, which will have varying effects in different agricultural ecological zones (AEZs).
